"Clubbed thumb" is a misnomer for stub(by) thumb, known clinically as brachydactyly type D, or BDD. BDD is a harmless genetic trait characterized by the last bone of one or both thumbs being short and round with an accompanying short and wide nail bed. They derive from the Dogon tribe residing in Africa.
The condition is also sometimes known as potter's thumb or royal thumb but mostly referred to as a stubby thumb.
